Preheat your oven to 400 degrees Fahrenheit to ensure even cooking.

Carefully slice the sweet potato into even 1/4 to 1/2-inch thick slices using a mandoline or sharp knife.

Optional: Lightly brush both sides of each slice with olive oil for extra crispness.

Arrange the slices in a single layer on a parchment-lined baking sheet to prevent sticking.

Bake for 30 minutes, flipping halfway through, until the slices are soft in the center and lightly toasted around the edges.

For thicker slices, you may need to add 5-10 minutes to the baking time.

Once cooled, store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, simply toast them in the oven or on a skillet.
